Learn about [image inputs](https://platform.openai.com/docs/guides/vision). - `class BetaResponseInputFile` A file input to the model. - `version: String` Optional version of the prompt template. - `prompt_cache_key: String` Used by OpenAI to cache responses for similar requests to optimize your cache hit rates. Replaces the `user` field. [Learn more](https://platform.openai.com/docs/guides/prompt-caching). - `prompt_cache_options: PromptCacheOptions{ mode, ttl}` Options for prompt caching. Supported for `gpt-5.6` and later models. By default, OpenAI automatically chooses one implicit cache breakpoint. You can add explicit breakpoints to content blocks with `prompt_cache_breakpoint`. Each request can write up to four breakpoints. For cache matching, OpenAI considers up to the latest 80 breakpoints in the conversation, without a content-block lookback limit. Set `mode` to `explicit` to disable the implicit breakpoint. The `ttl` defaults to `30m`, which is currently the only supported value. See the [prompt caching guide](https://platform.openai.com/docs/guides/prompt-caching) for current details. - `mode: :implicit | :explicit` Controls whether OpenAI automatically creates an implicit cache breakpoint. Defaults to `implicit`. With `implicit`, OpenAI creates one implicit breakpoint and writes up to the latest three explicit breakpoints in the request. With `explicit`, OpenAI does not create an implicit breakpoint and writes up to the latest four explicit breakpoints. If there are no explicit breakpoints, the request does not use prompt caching. - `:implicit` - `:explicit` - `ttl: :"30m"` The minimum lifetime applied to every implicit and explicit cache breakpoint written by the request. Defaults to `30m`, which is currently the only supported value. The backend may retain cache entries for longer. - `:"30m"` - `prompt_cache_retention: :in_memory | :"24h"` Deprecated. Use `prompt_cache_options.ttl` instead. The retention policy for the prompt cache. Set to `24h` to enable extended prompt caching, which keeps cached prefixes active for longer, up to a maximum of 24 hours. [Learn more](https://platform.openai.com/docs/guides/prompt-caching#prompt-cache-retention). This field expresses a maximum retention policy, while `prompt_cache_options.ttl` expresses a minimum cache lifetime. The two fields are independent and do not interact. For `gpt-5.5`, `gpt-5.5-pro`, and future models, only `24h` is supported. For older models that support both `in_memory` and `24h`, the default depends on your organization's data retention policy: - Organizations without ZDR enabled default to `24h`. - Organizations with ZDR enabled default to `in_memory` when `prompt_cache_retention` is not specified. - `:in_memory` - `:"24h"` - `reasoning: Reasoning{ context, effort, generate_summary, 2 more}` **gpt-5 and o-series models only** Configuration options for [reasoning models](https://platform.openai.com/docs/guides/reasoning). - `context: :auto | :current_turn | :all_turns` Controls which reasoning items are rendered back to the model on later turns.

Only set this when you set `stream: true`. - `include_obfuscation: bool` When true, stream obfuscation will be enabled. Stream obfuscation adds random characters to an `obfuscation` field on streaming delta events to normalize payload sizes as a mitigation to certain side-channel attacks. These obfuscation fields are included by default, but add a small amount of overhead to the data stream. You can set `include_obfuscation` to false to optimize for bandwidth if you trust the network links between your application and the OpenAI API. - `temperature: Float` What sampling temperature to use, between 0 and 2.

[Learn more](https://platform.openai.com/docs/guides/safety-best-practices#safety-identifiers). - `service_tier: :auto | :default | :flex | 2 more` Specifies the processing type used for serving the request. - If set to 'auto', then the request will be processed with the service tier configured in the Project settings. Unless otherwise configured, the Project will use 'default'. - If set to 'default', then the request will be processed with the standard pricing and performance for the selected model. - If set to '[flex](https://platform.openai.com/docs/guides/flex-processing)' or '[priority](https://openai.com/api-priority-processing/)', then the request will be processed with the corresponding service tier. - When not set, the default behavior is 'auto'. When the `service_tier` parameter is set, the response body will include the `service_tier` value based on the processing mode actually used to serve the request. This response value may be different from the value set in the parameter. - `:auto` - `:default` - `:flex` - `:scale` - `:priority` - `status: BetaResponseStatus` The status of the response generation. One of `completed`, `failed`, `in_progress`, `cancelled`, `queued`, or `incomplete`. - `:completed` - `:failed` - `:in_progress` - `:cancelled` - `:queued` - `:incomplete` - `text: BetaResponseTextConfig` Configuration options for a text response from the model. Can be plain text or structured JSON data. Learn more: - [Text inputs and outputs](https://platform.openai.com/docs/guides/text) - [Structured Outputs](https://platform.openai.com/docs/guides/structured-outputs) - `format_: BetaResponseFormatTextConfig` An object specifying the format that the model must output. Configuring `{ "type": "json_schema" }` enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the [Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs). The default format is `{ "type": "text" }` with no additional options. **Not recommended for gpt-4o and newer models:** Setting to `{ "type": "json_object" }` enables the older JSON mode, which ensures the message the model generates is valid JSON. Using `json_schema` is preferred for models that support it. - `class Text` Default response format. Used to generate text responses. - `type: :text` The type of response format being defined. Always `text`. - `:text` - `class BetaResponseFormatTextJSONSchemaConfig` JSON Schema response format. Used to generate structured JSON responses.

Always `json_schema`. - `:json_schema` - `description: String` A description of what the response format is for, used by the model to determine how to respond in the format. - `strict: bool` Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the `schema` field. Only a subset of JSON Schema is supported when `strict` is `true`. To learn more, read the [Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs). - `class JSONObject` JSON object response format. An older method of generating JSON responses. Using `json_schema` is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so. - `type: :json_object` The type of response format being defined. Always `json_object`. - `:json_object` - `verbosity: :low | :medium | :high` Constrains the verbosity of the model's response.

Supported for `gpt-5.6` and later models. By default, OpenAI automatically chooses one implicit cache breakpoint. You can add explicit breakpoints to content blocks with `prompt_cache_breakpoint`. Each request can write up to four breakpoints. For cache matching, OpenAI considers up to the latest 80 breakpoints in the conversation, without a content-block lookback limit. Set `mode` to `explicit` to disable the implicit breakpoint. The `ttl` defaults to `30m`, which is currently the only supported value. See the [prompt caching guide](https://platform.openai.com/docs/guides/prompt-caching) for current details. - `mode: :implicit | :explicit` Controls whether OpenAI automatically creates an implicit cache breakpoint. Defaults to `implicit`. With `implicit`, OpenAI creates one implicit breakpoint and writes up to the latest three explicit breakpoints in the request. With `explicit`, OpenAI does not create an implicit breakpoint and writes up to the latest four explicit breakpoints.

This response value may be different from the value set in the parameter. - `:auto` - `:default` - `:flex` - `:scale` - `:priority` - `status: BetaResponseStatus` The status of the response generation. One of `completed`, `failed`, `in_progress`, `cancelled`, `queued`, or `incomplete`. - `:completed` - `:failed` - `:in_progress` - `:cancelled` - `:queued` - `:incomplete` - `text: BetaResponseTextConfig` Configuration options for a text response from the model. Can be plain text or structured JSON data. Learn more: - [Text inputs and outputs](https://platform.openai.com/docs/guides/text) - [Structured Outputs](https://platform.openai.com/docs/guides/structured-outputs) - `format_: BetaResponseFormatTextConfig` An object specifying the format that the model must output. Configuring `{ "type": "json_schema" }` enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the [Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs). The default format is `{ "type": "text" }` with no additional options. **Not recommended for gpt-4o and newer models:** Setting to `{ "type": "json_object" }` enables the older JSON mode, which ensures the message the model generates is valid JSON. Using `json_schema` is preferred for models that support it. - `class Text` Default response format. Used to generate text responses. - `type: :text` The type of response format being defined. Always `text`. - `:text` - `class BetaResponseFormatTextJSONSchemaConfig` JSON Schema response format. Used to generate structured JSON responses. Learn more about [Structured Outputs](https://platform.openai.com/docs/guides/structured-outputs). - `name: String` The name of the response format. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64. - `schema: Hash[Symbol, untyped]` The schema for the response format, described as a JSON Schema object. Learn how to build JSON schemas [here](https://json-schema.org/). - `type: :json_schema` The type of response format being defined. Always `json_schema`. - `:json_schema` - `description: String` A description of what the response format is for, used by the model to determine how to respond in the format. - `strict: bool` Whether to enable strict schema adherence when generating the output. If set to true, the model will always follow the exact schema defined in the `schema` field. Only a subset of JSON Schema is supported when `strict` is `true`. To learn more, read the [Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs). - `class JSONObject` JSON object response format. An older method of generating JSON responses. Using `json_schema` is recommended for models that support it. Note that the model will not generate JSON without a system or user message instructing it to do so. - `type: :json_object` The type of response format being defined. Always `json_object`. - `:json_object` - `verbosity: :low | :medium | :high` Constrains the verbosity of the model's response. Lower values will result in more concise responses, while higher values will result in more verbose responses. Currently supported values are `low`, `medium`, and `high`. - `:low` - `:medium` - `:high` - `top_logprobs: Integer` An integer between 0 and 20 specifying the maximum number of most likely tokens to return at each token position, each with an associated log probability. In some cases, the number of returned tokens may be fewer than requested. - `truncation: :auto | :disabled` The truncation strategy to use for the model response. - `auto`: If the input to this Response exceeds the model's context window size, the model will truncate the response to fit the context window by dropping items from the beginning of the conversation. - `disabled` (default): If the input size will exceed the context window size for a model, the request will fail with a 400 error. - `:auto` - `:disabled` - `usage: BetaResponseUsage` Represents token usage details including input tokens, output tokens, a breakdown of output tokens, and the total tokens used. - `input_tokens: Integer` The number of input tokens. - `input_tokens_details: InputTokensDetails{ cache_write_tokens, cached_tokens}` A detailed breakdown of the input tokens. - `cache_write_tokens: Integer` The number of input tokens that were written to the cache. - `cached_tokens: Integer` The number of tokens that were retrieved from the cache. [More on prompt caching](https://platform.openai.com/docs/guides/prompt-caching). - `output_tokens: Integer` The number of output tokens. - `output_tokens_details: OutputTokensDetails{ reasoning_tokens}` A detailed breakdown of the output tokens. - `reasoning_tokens: Integer` The number of reasoning tokens. - `total_tokens: Integer` The total number of tokens used. - `user: String` This field is being replaced by `safety_identifier` and `prompt_cache_key`.

It includes all descendants—children, grandchildren, and deeper subagents—but excludes the root agent. The API does not impose a fixed upper bound on this setting. The default is `3`, which is recommended for most workloads. Multi-agent runs also have no fixed limit on tree depth or the total number of subagents created during a run. - `parallel_tool_calls: bool` Whether to allow the model to run tool calls in parallel. - `previous_response_id: String` The unique ID of the previous response to the model. Use this to create multi-turn conversations. Learn more about [conversation state](https://platform.openai.com/docs/guides/conversation-state).

Supported for `gpt-5.6` and later models. By default, OpenAI automatically chooses one implicit cache breakpoint. You can add explicit breakpoints to content blocks with `prompt_cache_breakpoint`. Each request can write up to four breakpoints. For cache matching, OpenAI considers up to the latest 80 breakpoints in the conversation, without a content-block lookback limit. Set `mode` to `explicit` to disable the implicit breakpoint. The `ttl` defaults to `30m`, which is currently the only supported value. See the [prompt caching guide](https://platform.openai.com/docs/guides/prompt-caching) for current details. - `mode: :implicit | :explicit` Controls whether OpenAI automatically creates an implicit cache breakpoint. Defaults to `implicit`. With `implicit`, OpenAI creates one implicit breakpoint and writes up to the latest three explicit breakpoints in the request. With `explicit`, OpenAI does not create an implicit breakpoint and writes up to the latest four explicit breakpoints. If there are no explicit breakpoints, the request does not use prompt caching. - `:implicit` - `:explicit` - `ttl: :"30m"` The minimum lifetime applied to every implicit and explicit cache breakpoint written by the request. Defaults to `30m`, which is currently the only supported value. The backend may retain cache entries for longer. - `:"30m"` - `prompt_cache_retention: :in_memory | :"24h"` Deprecated. Use `prompt_cache_options.ttl` instead. The retention policy for the prompt cache. Set to `24h` to enable extended prompt caching, which keeps cached prefixes active for longer, up to a maximum of 24 hours. [Learn more](https://platform.openai.com/docs/guides/prompt-caching#prompt-cache-retention). This field expresses a maximum retention policy, while `prompt_cache_options.ttl` expresses a minimum cache lifetime. The two fields are independent and do not interact. For `gpt-5.5`, `gpt-5.5-pro`, and future models, only `24h` is supported. For older models that support both `in_memory` and `24h`, the default depends on your organization's data retention policy: - Organizations without ZDR enabled default to `24h`. - Organizations with ZDR enabled default to `in_memory` when `prompt_cache_retention` is not specified. - `:in_memory` - `:"24h"` - `reasoning: Reasoning{ context, effort, generate_summary, 2 more}` **gpt-5 and o-series models only** Configuration options for [reasoning models](https://platform.openai.com/docs/guides/reasoning). - `context: :auto | :current_turn | :all_turns` Controls which reasoning items are rendered back to the model on later turns.

Currently supported values are `none`, `minimal`, `low`, `medium`, `high`, `xhigh`, and `max`. Reducing reasoning effort can result in faster responses and fewer tokens used on reasoning in a response. Not all reasoning models support every value. See the [reasoning guide](https://platform.openai.com/docs/guides/reasoning) for model-specific support. - `:none` - `:minimal` - `:low` - `:medium` - `:high` - `:xhigh` - `:max` - `generate_summary: :auto | :concise | :detailed` **Deprecated:** use `summary` instead. A summary of the reasoning performed by the model. This can be useful for debugging and understanding the model's reasoning process. One of `auto`, `concise`, or `detailed`. - `:auto` - `:concise` - `:detailed` - `mode: String | :standard | :pro` Controls the reasoning execution mode for the request. When returned on a response, this is the effective execution mode. - `String = String` - `Mode = :standard | :pro` Controls the reasoning execution mode for the request. When returned on a response, this is the effective execution mode. - `:standard` - `:pro` - `summary: :auto | :concise | :detailed` A summary of the reasoning performed by the model. This can be useful for debugging and understanding the model's reasoning process. One of `auto`, `concise`, or `detailed`. `concise` is supported for `computer-use-preview` models and all reasoning models after `gpt-5`. - `:auto` - `:concise` - `:detailed` - `safety_identifier: String` A stable identifier used to help detect users of your application that may be violating OpenAI's usage policies. The IDs should be a string that uniquely identifies each user, with a maximum length of 64 characters. We recommend hashing their username or email address, in order to avoid sending us any identifying information. [Learn more](https://platform.openai.com/docs/guides/safety-best-practices#safety-identifiers). - `service_tier: :auto | :default | :flex | 2 more` Specifies the processing type used for serving the request. - If set to 'auto', then the request will be processed with the service tier configured in the Project settings. Unless otherwise configured, the Project will use 'default'. - If set to 'default', then the request will be processed with the standard pricing and performance for the selected model. - If set to '[flex](https://platform.openai.com/docs/guides/flex-processing)' or '[priority](https://openai.com/api-priority-processing/)', then the request will be processed with the corresponding service tier. - When not set, the default behavior is 'auto'. When the `service_tier` parameter is set, the response body will include the `service_tier` value based on the processing mode actually used to serve the request. This response value may be different from the value set in the parameter. - `:auto` - `:default` - `:flex` - `:scale` - `:priority` - `store: bool` Whether to store the generated model response for later retrieval via API. - `stream: bool` If set to true, the model response data will be streamed to the client as it is generated using [server-sent events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events#Event_stream_format). See the [Streaming section below](https://platform.openai.com/docs/api-reference/responses-streaming) for more information. - `stream_options: StreamOptions{ include_obfuscation}` Options for streaming responses. Only set this when you set `stream: true`. - `include_obfuscation: bool` When true, stream obfuscation will be enabled. Stream obfuscation adds random characters to an `obfuscation` field on streaming delta events to normalize payload sizes as a mitigation to certain side-channel attacks. These obfuscation fields are included by default, but add a small amount of overhead to the data stream. You can set `include_obfuscation` to false to optimize for bandwidth if you trust the network links between your application and the OpenAI API. - `temperature: Float` What sampling temperature to use, between 0 and 2. Higher values like 0.8 will make the output more random, while lower values like 0.2 will make it more focused and deterministic.

Configuring `{ "type": "json_schema" }` enables Structured Outputs, which ensures the model will match your supplied JSON schema. Learn more in the [Structured Outputs guide](https://platform.openai.com/docs/guides/structured-outputs). The default format is `{ "type": "text" }` with no additional options. **Not recommended for gpt-4o and newer models:** Setting to `{ "type": "json_object" }` enables the older JSON mode, which ensures the message the model generates is valid JSON. Using `json_schema` is preferred for models that support it. - `class Text` Default response format. Used to generate text responses. - `type: :text` The type of response format being defined. Always `text`. - `:text` - `class BetaResponseFormatTextJSONSchemaConfig` JSON Schema response format. Used to generate structured JSON responses.

Always `json_object`. - `:json_object` - `verbosity: :low | :medium | :high` Constrains the verbosity of the model's response. Lower values will result in more concise responses, while higher values will result in more verbose responses. Currently supported values are `low`, `medium`, and `high`. - `:low` - `:medium` - `:high` - `tool_choice: BetaToolChoiceOptions | BetaToolChoiceAllowed | BetaToolChoiceTypes | 6 more` How the model should select which tool (or tools) to use when generating a response. See the `tools` parameter to see how to specify which tools the model can call. - `BetaToolChoiceOptions = :none | :auto | :required` Controls which (if any) tool is called by the model. `none` means the model will not call any tool and instead generates a message. `auto` means the model can pick between generating a message or calling one or more tools. `required` means the model must call one or more tools. - `:none` - `:auto` - `:required` - `class BetaToolChoiceAllowed` Constrains the tools available to the model to a pre-defined set. - `mode: :auto | :required` Constrains the tools available to the model to a pre-defined set. `auto` allows the model to pick from among the allowed tools and generate a message. `required` requires the model to call one or more of the allowed tools. - `:auto` - `:required` - `tools: Array[Hash[Symbol, untyped]]` A list of tool definitions that the model should be allowed to call.
